Don't laugh... no really Fiero GT swap advise wanted
I bought my wife a 1986 Fiero like she once had and and really enjoyed. We have quite a collection of low budget cars we like going so I thought I would add another. Anyhow, as you all know these cars are not dragstrip rippers and I am not looking to make one of it. I just want enough power to make it fun to drive without tearing up the transaxle constantly. There are two swaps I am considering because I want to stay V6 and gain HP Tuners support. I would like to find a DOHC 3.4L Z34 donor car or a series 2 3.8L supercharged donor car, also HP Tuner compatible. What I would like to find from you guys or possibly someone you all know with one of these already done so I can see one in person. Thanks for any help.
They are hard to keep cool. Before the EEeemernet craze, I had a Fiero with a 125 shot. So embarrassing to drive but so much fun. Burned that damn thing to the ground.
LS swap that beast and be done with it. A FWD 5.3 car should have everything you need shouldn't it?
While I realize everything is better with an LS swap, there are starter provisions and other things that make it an expensive pain. I also want to play with boost cheap and both of the above mentioned motors will provide that possibility.
the sc 3800 swap would be your best option, it works with HP tuners and makes good power on a budget.
Yes sir, and they are a lot more common than the 3.4L DOHC (also HP tuner compatible). I just thought the 3.4 would make a really cool turbo platform. Rumor has it the that little motor made 275hp until GM had too detune before production for a lack of a strong trans axle.
I have done a sbc/standard & auto trans, 4.9 Cadillac/auto trans, 3800sc/auto trans, LS4/auto trans all in different Fieros. For the money 3800sc is the best bang for the buck and the least amount of fab work. There a few guys who make swap harness for the 3800sc that makes it super easy.
For a quick fun ride the 3800sc is great, but your going to be maxxed out at 350-375hp unless you drop some coin on cam, pulley, headers.
go over to Pennock's Fiero Forum www.fiero.nl and search.
Been there and done that. This sight is much easier to navigate and I am mostly looking for a Houston area car to look at in person. People here are much more active than Pennocks and besides, I know a **** load of people over here.
3.8 would be a good option, swaps been done and through the FWD plat forms that ran that engine, ZZP, etc they have a lot of solid after market support.
I have a friend that did an an 3.8 swap in his what do you need to know or see I can try to get some pictures and details for you
Mostly looking for a car around the Houston area to reference as I build. I am sure I will get it figured out one way or another. I am finding supercharger kits even for the non-supercharger motors so I may do one of those with a turbo. I really want to play around with a turbo setup. I can remember some really fun times driving a four cylinder T-bird turbo coupe. Laaaaaaag....booooost, shift. LOL
